How a thermal roof survey works in Fratton
A thermal camera can help when the cause of damp isn’t obvious. Water can travel some distance under a roof covering before it shows inside, and the camera can show patterns that help us follow it. The images are used alongside a visual inspection and moisture readings, so no conclusion rests on one method alone. If you’ve noticed leaks that are hard to trace and wet insulation beneath the membrane, a survey will tell you what’s going on.
Places like Fratton can be near small airfields or other airspace restrictions, so the Drone Safety Map is checked before any flight. Open ground can mean stronger wind, which also affects whether a small drone can fly. Each flight is planned with neighbours’ privacy in mind, as well as the airspace and the wind.
Pictures do a lot of the work in our reports, because a photo of a cracked flashing says more than a paragraph. If something couldn’t be seen safely, the report is clear about it.

Thermal roof surveys in Fratton: local notes
The coast is about 2 miles or less from Fratton. Thermal imaging works best after a sunny day, with a dry roof surface and little wind, so the date is chosen with the forecast in mind. A number of Hampshire villages keep thatched roofs on their older buildings. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile. A drone or thermal camera adds most on the steep, tall and hidden parts of roofs like these.
Shop and office owners around The Bridge Shopping Centre may find that a commercial roof can be photographed from above without anyone walking on it. If you live in an older home near St Mary's Church, tall stacks and steep slopes are easier to judge with close-up aerial photos than from the pavement.
Fratton is about 1 mile south-east of Portsmouth, in Portsmouth. We cover Fratton and the rest of Portsmouth. Our Portsmouth coverage includes Fratton and the places around it.
Here we cover the PO1, PO4 and PO3 postcode area for thermal roof surveys. We cover properties on Renny Road, Clive Road and Union Road. With the A288 close by, Fratton is simple for us to get to for thermal roof surveys. If you are just outside Fratton, we cover Kingston (1 mile north-east), Portsmouth (1 mile north-west), Landport (1 mile west), Baffins (1 mile north-east) and Copnor (1 mile north-east). Larger places within reach include Wymering (3 miles north), Paulsgrove (3 miles north), Cosham (3 miles north), Drayton (3 miles north) and Farlington (4 miles north-east).
What’s near Fratton
We work in homes and buildings around The Portsmouth Academy, Alexandra Park and St Edmund's Catholic School and the streets around them. There is a railway station in Fratton itself: Fratton station. A little further out are St Mary's Hospital (within half a mile east) and Charles Dickens Birthplace Museum (0.8 miles north-west). The countryside around Fratton includes Milton Locks and Portsdown Hill.
What we are asked to look at in Fratton
Not every roof problem shows on the surface. Wet insulation, gaps in insulation and heat loss are frequently invisible from outside. A thermal camera adds another way of finding them.
Things that frequently lead to a survey include:
- Water getting in at parapets and stacks
- Damp that repairs haven’t cured
- Wet areas near outlets and upstands
- Cold spots on ceilings under the roof
Take a building like Penhale Infant School & Nursery: a view from above covers a wide roof far faster than walking it.
Choosing a roof surveyor
- Whether the roof space is looked at, where there is one
- Their drone registration, if they fly one
- What they won’t be able to tell you
- Their track record with similar roofs
What happens on the day
Before we start, tell us why you’ve booked: buying, a leak, storm damage, new work or just wanting to know where things stand. That way we can focus on what matters to you. The visit usually takes an hour or two on an ordinary house, or half a day or so for a commercial building. Being in a smaller place like Fratton doesn’t change how the visit works: outside, inside and from any safe vantage point, in that order. Point out any stains, cracks or loose pieces you’ve spotted.
- First we discuss the roof, any damp and the forecast for the visit.
- The roof is inspected visually from safe positions.
- We take thermal images of the roof and of the loft where we can reach it.
- We take moisture readings where the images suggest a problem.
- The report pairs each thermal image with a photo and explains what it suggests.
Before we arrive
- Gather any invoices or paperwork from past roof work
- Leave side gates unlocked
- Make a note of anything you’d like us to look at
Booking a survey
Booking is simple: just ring 07833 053749 or drop us an email and give us some details about the property and we will explain which survey suits. We confirm the price before anything is booked.

Fratton: your questions answered
Is Fratton in the area you cover?
Yes, Fratton is one of the places we work. Every survey there gets the same written report with photos.
Will you come out to Fratton?
Yes, smaller places are covered as well as towns. We cover the whole of London and South East England. Just mention lanes, gates or anything else about the route when you book.
Do you carry out surveys on Saturdays and Sundays?
Surveys run on weekdays, Saturdays and Sundays. To find a day that suits you, call 07833 053749 or send us an email.
Can you do a thermal survey in any weather?
Conditions on the day affect the results. A sunny day beforehand, a dry surface and calm air all help. Rain, wind and heavy cloud can weaken the patterns, so we discuss the forecast when booking.
How do I arrange a thermal roof survey in Fratton?
Just ring 07833 053749 or email us. We’ll ask a few questions, confirm the price and agree a date, weekday or weekend.
Is it a structural engineer’s report?
No. We point out what can be seen, such as sagging or deflection, but we’re not structural engineers and do not carry out calculations. If we think you need an engineer, the report says so.
Does thermal imaging detect leaks directly?
Thermal imaging shows temperature rather than water. Wet insulation holds heat longer than dry, so it can stand out, but we check each finding with moisture readings.
Tips that help
Most of what helps is simple and safe from ground level. A few suggestions:
- Heat the home normally on the days before
- Keep a record of when stains appear
- Keep outlets and gutters clear to stop water sitting
- Take photos of stains as they appear, so we can compare
You can pass the report to a roofer so they can see where the problem areas seem to be. Each thermal image is matched to a normal photo, so the areas are easy to locate.
Check loft insulation covers the whole area and hasn’t been disturbed. Gaps frequently appear after work in the loft.
Roof by roof
Pitched slate and tile roofs
Slate and tile roofs are often harder to read with a thermal camera, because of the air space beneath. We combine the images with an inspection from the loft where there is safe access.
Loft insulation
The difference is clearest when the home is heated and it’s cold out. We explain in the report how the conditions on the day affected what we saw.
Honest limits
No survey can tell you everything, and we’d rather be clear about that before booking. Keep these in mind:
- Hidden layers that need to be opened up to check
- An energy rating for the building
- Reliable images in rain, strong wind or on a wet roof surface
If in doubt, phone 07833 053749 or send us an email and we’ll point you to the right survey before booking. The full list of what we check.
